DANGER SIGNAL.

Original application tiled April 26, 1920, Serial No. 376,673. Dividedand this application filed June 27,

'l`hc present invention relates to signaling devices, such as areadapted tobe located at dangerous points along the roadway or atintersections or cross roads or -railroad crossings. and is a divisionof my pending application serial No. 376,673, filed April Q6, 1920, andrelates more especially to the reflector which forms a part of thesignaling device.

The objects-of the present invention are to provide a signaling deviceof the general character referred to which will Vreflect the rays oflight from the headlight of an approaching vehicle, back to the operatorof the vehicle or to the operator of another vehicle approaching fromanother direction.

Another object of the invention is to provide such a signaling devicewith a transpai-,

ent color reflecting medium including a plurality of angular or convexand concave surfaces provided with mirror back and arranged toreflectrays of light in different directions.

The above together with other `objects which will be apparent from thefollowing description and the accompanying drawings, may be attained byforming the reflector of a single sheet of colored transparent materialpressed into the form of a plurality of hollow shallow pyramids, eachcomprising four triangular reflecting surfaces arranged to receive thelight, and reflect it in a different direction, the reflected rays beingpassed through the colored reflecting medium, a suitable mirror backbeing applied to the rear or inner face of the colored medium.

With these objects in view, the invention consists in the novelconstructionv and arrangement of parts, hereinafter described,illustrated in the accompanying drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform, proportions, size and minor details of construction may be madewithin the scope of the appended claims, without departing from thespirit or sacrificing any of the advantages of the invention.

The invention thus set forth in general terms isillustrated in theaccompanying drawings forming part hereof, in Which- Figure l is a frontelevation of a signaling device provided with a reflector embodying theinvention; and Fig. 2, a sectional view through the relector upon anenlarged scale.

Serial' No. 480,902.

I A practical embodilnent of the invention is disclosed in theaccon'ipauying drawings, forming a part of this specification 'in whichsimilar numerals of reference indicate corresponding parts throughoutthe several views.

The signaling device is preferably mounted upon a post l which may heimbedded in the ground at any desired point along a roadway or at across road or at a railroad crossing. rl`he frame 2 which contains therefiector may be provided with a collar 3 which receives the upper endot' the post 1 and is held in any desired radial position thereon bymeans of the set screw 4l. 'lhe reflecting medium indicated generally bythe numeral 5 comprises a single sheet of colored glass or othertransparent material which is coated upon its rear surface with mercuryor the like in the manner of a mirror as shown at 6.

This reflecting medium is pressed into the form shown in the drawingsproducing a plurality of rectangular sections indicated generally by thenumeral 7, each section being in the form of a shallow pyramidcomprising a plurality of triangular faces 8 set at angles to eachother, the vertex of each pyramid being preferably convex, as shown at9.

By forming the face of the reflecting medium in the manner shown, all ofthe rays from an` approaching light will strike upon the refiectorand bereected back to the operator of an approaching vehicle, being colored bypassing through the colored refleeting medium. When a light is thrownupon the signal, it will appear as a brilliant colored square,instantlyl attractingthe attention of persons approaching the signal andgiving Warning of danger.

I claim 1. In a signaling device, a support, aframe mounted upon thesupport, and a reflecting plate carried in the frame comprising atransparent, colored, `medium pressed/into a series of liollow pyramidshaving a reflecting mediuml upon the lhollow sides thereof forming aplurality of angularly disposed retiecting surfaces arranged to divergerays' of white light falling thereon and color the light which isreflected back therefrom.

2. In a signaling device, a support, a frame mounted upon the support,and a reflecting plate carried in the frame comprising a transparent`colored meduuu including a plurality of hollow pyramidal units havingrreflecting mediums upon their hollow sides, each unit having a pluralityof angnlarly disposed reflecting surfaces arranged to diverge rays ofwhite light falling thereon and color the light which is reflected hacktherefrom.

3. ln a signaling device, a reflecting plate comprising a coloredtransparent medium pressed into a series of hollow pyramids having a.reflectingl medium upon the hollow sides ther-cof forming a plurality ofangularl v disposed reflecting surfaces arranged to diverge ravs ofwhitelight fallingl thereon and color the light which is reflected hacktherefrom.

at. ln a signaling device` a reflecting plate comprising a coloredtransparent medium including a plurality of hollow pyramidal units, areflecting medium upon the hollow side thereof, each unit having aplurality of angular-ly disposed reflcctingz;l surfaces arranged todiverge rays of white light falling thereon and color the light which isreflected hack therefrom.

5. In a signaling device, a reflecting plate comprising a coloredtransparent medium pressed into a series of hollow pyramids having areflecting,r medium `np'on the hollow face thereof forming a centralconvex surface and a plurality of antrnlarl)v disposed reflectingsurfaces arranged to diverge rays of white light falling thereon andcolor the light which is reflected back therefrom.

G. In a signaling device, a refiecting mcdium comprising a transparentcolored plate pressed into a hollow pyramidal form and a rcftector ofcorresponding shape upon the rear side of said transparent plate.

T. In a signaling' device, a reflecting medium comprisingr a transparentcolored plate of hollow pvramidal form having a mirror ha el: upon itsconcave surface.

8. lu a .signaling device, a reflecting medium comprising a transparentcolored plate comprising a plurality of shallow, hollow pyramids and amirror hack upon the concave surfaces thereof.

f). In a signal device, a reflecting medium comprising a transparent,colored plate pressed into a hollow, pyramidal form having a roundedapex and a reflector of corresponding shape upon the rear side of saidtransparent plate.

In testimony that I claim the ahove, l have hereunto subscribed my name.
